Here is their summation:
To sum up, for long and happy LFP battery life, in order of importance, you should be mindful of the following:
Keep the battery temperature under 45 Centigrade (under 30C if possible) – This is by far the most important!!
Keep charge and discharge currents under 0.5C (0.2C preferred)
Keep battery temperature above 0 Centigrade when discharging if possible – This, and everything below, is nowhere near as important as the first two
Do not cycle below 10% – 15% SOC unless you really need to
Do not float the battery at 100% SOC if possible
Do not charge to 100% SOC if you do not need it
That's a lot of restrictions for a battery that costs at least 10x what a lead acid costs. Operating temp 30C?! horse hockey! Charge current 0.2 to 0.5C, that's terrible.
